It became clear that armed individuals named as US special forces stationed in Afghanistan engage in harassing, annoying, torturing and even murdering innocent people. http://www.bbc.co.uk/news/world-asia-21566295 http://www.pbs.org/wgbh/pages/frontline/secret-war/ A recent example in the province is an incident in which nine people were disappeared in an operation by this suspicious force and in a separate incident a student was taken away at night from his home, whose tortured body with throat cut was found two days later under a bridge. There are some individuals, some Afghans, who are working within these cells, within these [US] special forces groups. The accountability of US forces and local militia working with them has been a growing source of friction in Afghan-US relations. Afghan forces ask for air support from foreigners and children get killed in an air strike.
